PM Surya Ghar – Muft Bijli Yojana
A Government of India scheme to promote rooftop solar for households by providing subsidies and enabling consumers to generate their own electricity and reduce power bills.
1) Scheme overview, eligibility & subsidy framework
Objective: Install rooftop solar systems in residential homes and provide free/low-cost electricity.
Eligibility:
•    Indian residential households
•    Valid electricity connection
•    Roof ownership/usage rights
•    Not availing subsidy for the same system earlier
Subsidy framework (indicative):
•    Up to 2 kW: high subsidy support
•    2–3 kW: additional subsidy slab
•    Above 3 kW: capped subsidy
(Actual subsidy notified by MNRE & state DISCOM)
Benefits:
•    Lower electricity bills
•    Net-metering income (where applicable)
•    Clean energy adoption

3) Rooftop capacity & savings calculator (concept)
System size depends on:
•    Monthly electricity consumption
•    Available roof area
•    Budget
Indicative rule:
•    1 kW solar → ~100–120 units/month generation
•    1 kW requires ~10 sq. meters roof area
Savings estimate:
•    2 kW → major bill reduction
•    3 kW → near-zero bill for average homes
•    5 kW → surplus generation possible
Subsidy Framework (MNRE + Rajasthan State)
Central Financial Assistance (MNRE)
•    Up to 1 kW – Rs 30,000 subsidy
•    Up to 2 kW – Rs 60,000 subsidy
•    Up to 3 kW and above – Rs 78,000 (maximum central subsidy cap)
Rajasthan State Additional Subsidy
•    Rs 17,000 per residential rooftop installation (as applicable under state support)
Total Benefit for Rajasthan Consumers (Indicative)
•    1 kW system → Rs 30,000 + Rs 17,000
•    2 kW system → Rs 60,000 + Rs 17,000
•    3 kW & above → Rs 78,000 + Rs 17,000
(Final subsidy disbursement subject to MNRE guidelines, DISCOM approval, and scheme conditions.)
